Definitions

  • the shade of the said pigment colors While retaining or even increasing their excellent fastness to light and alkalies, can be influenced by preparing the said green pigment color in the presence of basic dyestuffs, preferably those belonging to the malachite green series.
  • the process may be carried out for example by dissolving the nitroso-beta-naphthol in Water with the aid of a bisulfite, adding the iron salt in the manner described in the Patent No. 1,529,891 or in any other manner or in molecular proportions for example.
  • its bisulfite compound may also be employechpreferably with an addition of some excess of hisulfite solution.
  • cording to the present invention are faster at to light than a mere mechanical mixture of the iron compound of alpha-nitroso-betanaphthol with a basic dyestufl'. They are therefore thought to be a kind of complex compound, but applicantsdo not Wish to bind "*45 themselves to this expl n 7 F V 1116 partsof alpha-nitroso-betarnaphthol '-'.'What Wec-laim'is: f 1.
  • the process'of manufacturing pigment colors which comprises acting with an 113011 salt on nitroso-beta-naphthol in the j prese nce of a basic dyestulfand a substrate and precipitating thepigment color by meansjof an alkaline agent.
  • the process of manufacturing pigment V colors-"Which comprises mixingfan iron salt solution ⁇ with a solution of nitroso betanaphthol in a Water solutionofa bisulfite,
  • the process of manufacturing plgment colors which comprises mixing an iron salt solution with a solution of nitroso-betanaphthol in a bisulphite, adding an alkaline agent in a quantity insufficient for precipitation, adding diamond green BX, and precipitating the pigment color by means of an 9.
  • the process of manufacturing pigment Jcolors which comprises mixing a solution of about 48 parts of ferrous sulfate with a solution of about 167 parts of nitroso-betanaphthol in a bisulphite, adding an alkaline agent inaquantity insufficient for precipita- In testimony whereof we have hereunto set our hands.
  • composition is faster tolight than the mere mechanical mixture of the said two components, and which is obtained by acting a withan iron salt on nitroso-beta-naphthol in the presence of a basic dyestuff, and precipitating the pigment color by means of an alkaline agent.
